Compress PDF for USCIS — Meet the 6MB Upload Limit

Meets USCIS 6MB file limitFiles never storedFree — no signup

USCIS's online filing system caps each supporting document at 6MB. Scanned I-130 packages, I-485 evidence packets, and employment records often exceed this. Use this tool to compress them without losing legibility.

Official Requirements

Max per file
6 MB
Format
PDF
Min resolution
300 DPI recommended

Pro Tip: Scan at 200 DPI in grayscale rather than 300 DPI color for text-heavy documents like employment letters and bank statements. This can cut file size by 60% before you even compress.

How It Works

1

Upload your document

Select your I-130 evidence, police certificate, or any USCIS filing document.

2

Choose compression level

Use Balanced for standard docs; Strong if the file is still over 6MB after Balanced.

3

Compress

Redundant image data, embedded fonts, and metadata are stripped to reduce size.

4

Download & file online

Upload the compressed PDF directly to your USCIS online account.
